Re: Some IP subnet ignorance on call

Hi Sergey,

GnuGk can't ignore a call. The H.323 protocol requires that it either
accepts and routes a call or rejects it. You can use one of the many
authentication policies to define which calls should be rejected.

The other aspect is that once an H.323 endpoint is registered with a
gatekeeper, the endpoint _must_ place all its calls through the
gatekeeper. This ensures that you have a central security mechanism
which calls are allowed and which are not.

If your main gatekeeper is not within the local network and thus can't
reach private IPs, you can either use NAT traversal and proxy all
traffic in and out of the local network (simple, but inefficient) or
place an additional gatekeeper within the local network, which eg. uses
direct mode or routed mode and only routes calls to the outside
gatekeeper that must leave the local network. The later is the better
solution, but obviously requires installing multiple gatekeepers.

Regards,
Jan
